Abstract

The crystallographic features of the ferroelectric domain structures in (Sr1-xBax)Bi2Ta2O9 single crystals have been examined by transmission electron microscopy. The unique 90° domain structures were found in these single crystals. In SrBi 2Ta2O9 with x = 0, particularly the majority domains with the ±[110]t polarization vectors in the tetragonal notation arc divided by the minority ones with the ±[11̄0]t vectors, which were observed as a curved-line contrast in dark field images.
